DIMMER GLASSES.

Application filed June 9,

This invention relates to dimmer glasses, and especially'to' improvements on the-structure shown in my co-pending application entitled Dimmer glasses, filed October 31,

1923, Serial No. 671,928.

The object of the present invention is to generally improve and simplify the construction and operation of glasses of the character described, and particularly to provide means whereby the rims or supporting members of the dimming substance are mechanically attached to the nose-piece, directly, or through an intermediary part, wherein adequate range of lateral and vertical adjustment of the dimming medium may be obtained.

Evidently, a number ofmechanical structural variations may be used to obtain the object and purpose of this invention.

To further elucidate and amplify the several structures or modifications, reference will be made to the accompanying specification and drawings, in which- Fig. 1 is a rear view of the glasses.

Fig. 2 is a plan view of the nose-piece on which the lateral extensions are formed.

Fig. 3 is an enlarged detail section taken on line 3-3 of Fig. 1.

Figs. 4:, 5 and 6 show modified forms of the structure.

Referring to the drawings in detail, and particularly to Fig. l, A lndicates a nose piece and 2 a pair of lateral extensions formed thereon. Supported by the lateral extensions is a pair of angle brackets generally indicated at C, which serve as a support for the. dimming medium hereinafter to be described.

The angle brackets B are laterally adjustable on the extensions 2 and the spectacle frames C are vertically adjustable with relation to the angle brackets; the vertical and lateral adjustment obtained being of considerable importance as it permits adjustment of the dimming medium generally indicated at D with relation to the eyes of the wearer and a distant source of light which it is desired to dim. Lateraladjustment is obtained by slotting the lateral extensions, as indicated at 3, and by passing screws 4 through the angle brackets and the slotted portions of the lateral extensions 2. That is, the slots are sufficiently long to permit the angle brackets to 1924. Serial n... 718,851.

be moved laterally and then to be secured by the clamping screws when adjusted.

Vertical adjustment. is obtained by slotting the upright sections of the angle brackets and by securing the spectacle frames C thereto 'by means of clamping screws 5, the clamping screws passing through extensions 6' formed on the inner sides of the spectacle frames and disposed at right angles thereto, this particular construction beingpreferred as it permits of free access 't0 the screws when making the adjustment The spectacle frames proper may be rectangular in shape as shown, or they may be rounded or otherwise shaped as desired.

The bows indicated at E, whereby the glasses as a whole are secured, may be pivotally attached to the spectacle frames as indicated at 7, or they may be pivotally attached to the lateral extensions 2 as indicated at 8.

.The dimming medium D may be constructed of any suitable semi-transparent material, such as glass, celluloid or the like, and it may be colored yellow, green, blue. or otherwise as desired. The dimming medium is secured in the spectacle frames in any suitable manner and the remaining space may remain open or it may be filled in with lenses particularly suited to the wearer. this feature being of no particular importance as it is already fully described and completely disclosed in my copending application referred to. i

- Where the dimming medium alone is employed and supported in the upper left hand corners, a slightly out-of-balance condition -may exist, and to obviate this unbalanced condition a lateral extension is formed on the spectacle frames as indicated at 9. This extension forms a supportfor a pear-shaped weight 10, which is pivotally attached thereto and secured by means of a screw 11. By swinging the weight about its pivotal support, adjustment as far as balance is concerned may be readily obtained.-

In actual-use it will be noted that the space indicated at 12, whether open or covered by a lens, may be fully transparent so that the normal vision of the wearer will not be interfered with. I

The dimmer glasses are particularly intended forautomobile driving and the like posed and all blinding effects are obviated.-

The side of the road between the machine and the approaching machine still remains clear to the vision of the driver as this portion of the road is viewed through the unobstructed or clear portion 12 of the glasses.

The frame, comprising the nose-piece, the

.lateral extension, the. angle brackets, the

spectacle frames, etc., may be constructed of celluloid, metal or any suitable material. The lateral extensions 2 are preferably graduated, as shown, to facilitate lateral adjustment, and the vertical extensions of the angle brackets may similarly he graduated to facilitatevertical adjustment.

In Fig. 4, which is a modified form of the structure, .15 indicates the nose-piece, and formed thereon are two vertical arms 16. These arms are longitudinally slotted as shown for the reception of screws 17. 1B indicates a pair of angle-shaped-brackets attached to the vertical extensions 16 by means of the screws 17. 19 indicates a slot provided for the reception of screws 20, by means of which the spectacle frames or rims 21 are attached anteriorly to the members 18, the rims 21 being laterally adjustable with relation to the nose-piece and the members 18 by securing them in the manner here described. The slotted members 16 permit vertical adjustment and the slots 19 permit lateral adjustment.

The dimming medium is secured in any suitable manner, as indicated at 22, and the space shown at 23 may be occupied by a lens or clear glass, or it may be left entirely open. The bows are pivotally attached to the rims, as indicated at 24,-and as the bows are attached behind the ears of the wearer, the device as a whole isamply secured when in position.

Fig. 5 shows another modification, in which 25 indicates the nose-piece. This nose-piece is provided with two vertical arms or members 26 and these are vertically slotted as indicated. 27 indicates the spectacle rims and these are each provided with extensions 28 in which are formed horizontal slots 29. Screws F extend through the slots 26 and 29 and as such permit both vertical and lateral adjustment of the rims 27 in which the dimming medium 22 is supported. The dimming medium may in this instance be secured in any suitable manner and the open spaces ,23 may remain open or may have lenses or clear glass fitted therein as desired. The glasses are otherwise secured by means of bows 30.

In some instances it is desirable to do away with the lower part of the vertical rims entirely and with this object in View the modification shown in Fig. 6 is] presented. In this instance 32 indicates the nose-piece, "and this is provided with two vertical arms as indicated at 33, the arms being vertically slotted as at 34.

Two members such as indicated at 35, and in reality representing. the upper portion of a pair of spectacle rims, are secured to the extensions 34 by means of screws 36, the inner ends of the members 34-being longis tudinally'slotted as at 37 to permit lateral adjustment, and the slots 34 permitting ver-j tical adjustment.

The members 35 may be constructed of celluloid or a similar semi-transparent material, and" the dimming medium indicated at or to make it as a separate part, and in thatinstance itcould be secured to the arms 35 in any suitable manner. I

' I also wish it understood that other features of the i present invention may be changed within the scope of the appended claims, and that thefinish of the several parts employed may be such as the experience and judgment of the manufacturer may dictate or various uses may demand.

Having thus described my invention, what I claim and desire to secure by Letters Patent is r 36 may therefore be formed as a part there- 1. Eye glasses of the character described, 1
